j (C1. "s3-93) This invention relates to a device for'grinding and mixing' feeds.

Ari-object of the invention is the provision of and larger particles of the ingredients after which the ingredients are blown into an enclosed space whereby the ingredients will be intimately mixed and are ready then for disposal.

This invention will be best'understood from a consideration' of the following detailed descriping a part of the specification; nevertheless, it

is to beunderstood that the invention is 'not conned, to the disclosure, being susceptible 'of such changes and modifications as define no material departure from' the salient features of the invention as expressed in the appended claim.

In the drawing:

Fig. 1 is aV view in elevationof my combined.

mixer and grinder, Figure2 is a fragmentary enlarged vertical section of the device, and

Figure 3 is a transverse vertical section taken along the Iine 33 of Fig. 1.

Referring more particularly to the drawing, I0 designaftes a base member upon which is mounted a housing I I which forms a support for a tank I2. A chute I3 extends throughv an opening in the side wall of the housing I I and directly-opposite a conduit I4 which also communicates with the housing. The ingredients are fed into the upper open end of the chute I3 and are discharged into the housing whereby they are drawn into the conduit I4 by means of a centrifugal blower, generally designated by the numeral I5. 3,-and this blower consists of a driven shaft /I6 withvanes I'I attached thereto and terminating adjacent the inner periphery of a circular housing I8. This' housing is provided with a discharge spourt I9 which is in communication with the lowerend of av blower vpipe 20. The .upper end of the pipe, as shownat 2|, opens into the upper end of the tank I2 which forms a mixing chamber as will be presently described,

The blower ismounted on the. base member tion, in view of the accompanying drawing form- The blower is shown more particularly in Fig.

Ill, as shown at 25. A bracket 26 extends from the housing I8 and supports bearings 21 of the shaft 16'.. A pulley 28 is secured' to the outer end of .the shaft and is driven inJ any approved mannerl 5 cup 30 is connected by a'pipe 3l with the interior of the conduit I4 andthis cup is adapted tobe supplied withoils or other liquids which are drawn through the conduit' I4 by the suction ofthe blower I5. This liquid is thoroughly mixed 10 with the ingredients by. the revolving blade Il of the centrifugal blower. These blades not o yf' draw in the ingredients and force themthrough the pipe 20 but any lumps of the ingredients aire ground up and any of the ingredients which are 15 larger than are desired are also ground up by the revolving blades; The other ingredients may be meat or grains;

The lower end of `rthe tank I2, as shown at 32, is cone-shaped and has its lower end seated'20 within the upper end of the housing i2. A dis charge pipe 33 is connected to the lower reduced end, of the member 32 `and terminates labove lthe upper end of the conduit I4. A sleeve 34X is slidably mounted on the lower end of the discharge 25 pipe and this sleeve is adapted to be adjusted to 'various heights so' that its lower end 35 may be properly positioned imth respect to the diameter of the conduit I4 so that the materials issuingfrom the discharge pipe 33 will enter the conduit 30 I4 under the suction ci the blower I5.

A valve 40 is mounted on the shaft 4I and this shaft extends to the exterior of the member 32 so that it can be manually operated for closing or opening the valve 40 whendesired. f 3

I'he member 32 has adischarge opening 42.7

. which is normally closed by a gate valve 43 which `is adapted to be raised to permit the mixed ingredients from the tank lI2 to bedischarged and placed in bags or containers when desired. A 40 spout 44 embraces the opening 42 for directing the ingredients away from theA opening. While the spout 44 is shown located above the chute' I3,

. nevertheless it may be placed at right angles to a plane passing through the chute I3 for the 45 convenience of operation.

A dust collector 45 is mounted in .an opening in the upper end of thetank I2 and is adapted to prevent dust from the feed tankv from escaping to the air. 1

, 50 The operation `of my device is as follows: The

` ingredients are fed to the chute I3 in the proper then be drawn througnthe conduit I4 and into 55 the blower where they are not only ground'into f ne particles but 'they are mixed and forcedv upyvardly through thevpipe 2D and'into the tank l2. The valve 40 remains open initially so that the 'ingredients which enter 'thetank may be distial stages the valve 40 is closed for collecting' the material.v

From time to time the gate to permit the ingredients collected 'in the tank I2 to be discharged and bagged. 5

through the pipe 3| into the conduit I4. Due to the churning vaction of the lzglades of the blower l5 the liquids are then thoroughlymixed with the ingredients before the mixed ingredients are carried to the upper end of the tank I2..

I claim;0 l A combined 'feed grinder and mixer comprising a mixing tank having a discharge opening at valve 43 is raised When it is desired to add liquids to the in- 4 gredients the liquids are supplied in the proper "proportions through the cup-shaped member 30 2,222,380- t l y K the lower end, a discharge pipe projectingdown-` wardly from the lower open end of the tank, a housing securedv to the lower portion of the tank .and located in spaced relation with the pipe, a

centrifugal blower-grinder, a conduit connecting the inlet end of the blower-grinder with the housing below the end of the discharge pipe,

means feeding ingredients to thehousing and into the blower-grinder, a blower pipe connecty ing the discharge end of r the blower-grinder with the upper end of the tank' for conducting the mixed and groundingredients from the blower-grinder to the tank, means controlling the flow of the mixed ingredients from the tank to the incoming ingredients in the housing through the discharge pipe, a sleeve slidably mounted on the lower end of the discharge pipeand 'movable upwardly or downwardly so rthat the free end of the sleeve may bernovedtowards or away from the inlet end of the conduit where it opens into the housing, and *means*v operating the blower-- rgrinder.
